I APPARATUS FOR DRYING YARN WINDINGS PARTICULARLY OF PAPER YARN.

Specification of Letters Patent.

Application filed May 9, 1917. Serial No. 167,401,

To all whom it may concern:

Be it known that I, EMIL JAGENBERG, a subject of the German Emperor, and resident of 107 Himmelgeisterstrasse,. Dusseldorf, Germany, manufacturer, have invented certain new and useful Improvements in Apparatus for Dryin Yarn Windings Particularly of Paper Y arn, of which the following is a statement.

Cops or cross-reels, and in particular such of paper yarn which has, either previous to or during its manufacture been submitted to a moistening treatment, are, at the present time dried by placing them in large numbers into a box, in which heated air circulates. This method of drying has the drawback, that the air can act on the surface of the spools only, and that the inner portions thereof are not thoroughly dried notwithstanding a prolonged duration of the treatment. It is, however, not possible to leave the spools still longer in the drying chest until the inner portions are thoroughly dry, because a too long exposure to the action of the hot air would render the outer layers brittle. Owing to the inner layers being thus moist, this moistness frequently lead ing to a rotting, the tearing strength of the yarn is very irregular and low.

The present invention relates to a method and an arrangement by which an absolutely complete and uniform drying of the spools, both inside and outside is insured.

The feature of the novel method consists in that the cops or cross-reels are placed with their sleeves onto nozzles-and, if necessary into tubes, that said sleeves are closed at the front end and that lastly a current of suitably heated air is introduced into the sleeve and forcedto penetrate the layers of yarn so as to find an escape toward outside, during which passage the current of air will carry off all moisture. The drying eflect is further increased by the hot air circulating around the spools, by which particularly the outer layers will be dried. By

aid of the novel drying method described the drying process may be completed in one hour, while previously about nine hours were required for same. Furthermore the forcing. of the hot air through the yarn has the advantage thata very uniform and even higher tearing strength is obtained, which is of high importance for the subsequent weaving process.

The arrangement for carrying out the hereinbefore described method is exemplified in the accompanying drawings, in which Figure 1 is a front elevation, and Fig. 2 a side. elevation; Fig. 3 is a section on an enlarged scale of one of the spools; Fig. 4; is a similar section through a modification.

The arrangement which requires a small space consists essentially of an airtight casing g, the air in which may by means of a hot pipe it or the like be heated to a high temperature. The air is supplied or sucked out by aid of a fan or the like through a pipe Z. The casing g, which as shown in the drawings may be of a rectangular, a cylindrical or a spherical shape, is fitted as far as possible on all sides with preferably outwardly extending nozzles s, behind which valves '2; are disposed,.which, as dong as they are not opened, will prevent the air from escaping. The nozzle tubes serve to receive the sleeves, the cross-reels, cops and the like. The cross-reels is wound on perforated sleeves a are placed directly on the tubes, whilethe cops c are fitted into sockets or casings Z) which are fitted on the nozzles s; these'casings b closely inclose the cops but are left open at the top or have a perforated cap (Z which'can be removed. The outward ends of the spool sleeves are closed by means of stoppers p. To these stoppers stems i are attached which, on the stoppers being inserted open the valves o, and may if desirable, also serve to hold the spools. opening of the sleeves being thus closed by the stoppers p, the hot air introduced into the sleeves will penetrate the layers of yarn wound thereon and passes either transversely, through the perforations of the sleeves from inside out, or longitudinally through the windings of the incased cop. escaping at the top. The air-thus driven through the windings of the spools will carry all moisture with it, so that the spools will, as hereinbefore stated, be dried both quickly and evenly in all parts.

While one illustrative embodiment of the invention has been specifically described, it

is to be understood that variations may be made without departing from the spirit of Patented Feb. 3, 1920.

The outer air-tight casing Which lead the air current through the cops 01' cross-reels, means for heating said air current to a suitable temperature, valves fitted over the said nozzles,

means for holding said valves closed, and

stems in the nozzles for opening said valves when reels are fitted onto said nozzles.

'2. An apparatus for drying the yarn windings, particularly of paper yarns on cops, cross-reels and the like, comprising an air-tight casing, means of producing a cur rent of air through the same, nozzles through which said air current passes,

ineans for heating said air current to a suitable temperature, valves fitted over the said nozzles, means, such asstoppers, adapted to close the reel sleeves at the end opposite to the air entrance end, stems attached to said stoppers and adapted to operate on and open said valves when said stoppers are inserted.
